Currently using alsa-driver-hg20080126. Sound output is perfect.

The laptop has 2 build-in speakers and a built-in microphone and three
jacks in front: mic, line-in and headphones.

With: auto, acer, acer-aspire,3stack-dig I can record sound from
microphone but the quality is atrocious so barely usable.

With: targa-2ch-dig I have notice that the output is on both - the
speakers and the headphone whereas previously the output was changed
by plugging the headphones in.

Other options do not really make any difference apart from the number
of controls in the mixer.

In some cases the mic sound quality seems to be tiny bit better if I
switch to build-in microphone but it is far, far from good (and from
what I hear in my headphones when I enable microphone as output).
